Hydatid disease is rare in the United States, and an Echinococcus cyst occurring in the thigh muscles is rarer yet. At the Veterans' Administration Hospital, Cleveland, a case was encountered in 1952 in which a large cyst was found in the posterior thigh muscles and was surgically excised. This was the only case found clinically in some 76,308 admissions in the 10 years that the hospital has been open. During this same period 2611 autopsies* have been performed, and among them 3 other Echinococcus cysts, all of the liver, were encountered as incidental findings in patients who died of other conditions. On account of the rarity of reported cases of Echinococcus disease in this country, and because of the scarcity of references to it in the recent English literature, it appears worth while to report our case in detail.
